Specification of Letters Patent.

Patented June c, 1916.

Application filed May 14, 1914. Serial No. 838,515.

To all whom it may concern:

Be it known that I, FREDERICK M. FURBER, a citizen of the United States, residing at Revere, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Machines for Applying Stiffening Material to Parts of Boots and Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like reference'characters on the drawings indicating like parts in the several figures.

This invention relates to machine for applying stifiening material to parts of boots and shoes and is herein illustrated as embodied in a machine for applying shellac to the toe portion of the upper of a shoe.

In the manufacture of shoes it is customary to stiffen the toe portion of the upper so that in the finished shoe a so-called box toe will result. When the upper of a shoe is assembled in the process of manufacture there are commonly inserted at the toe portion one or more suitably shaped blanks'of fabric, leather or other suitable material to the surface of which is applied a coating of stiffening material just prior to the lasting operation, said stiffening material being liquid or viscous when applied but having the property of hardening after a short interval so that before the shoe has been removed from the last the stiffening material has become set to form the finished box toe. The base of the stiifening which is most commonly used at the present time is shellac and for brevity the present invention will be described in connection with'shellac although it should be understood that any suitable stiffening material may be used.

In my Patent No. 1,145,412 I have shown :a machine which is adapted for a similar presentation. The stiffening material, however, causes certain difliculties by reason of thefact that a surplusof it is supplied to the presenter and becomes gummed thereon.

One feature of the present invention compr ses improved means for supplying stilfening material to the presenter, and in the illustrated embodiment the presenter is at all times above the level of the stiffening material, means being provided for raising said material and supplying it to the presenter in comparatively small quantities.

Other features of the invention comprise improved mechanism for operating the presenter, and improved means for holding it removably upon its carrier so that it may be readily detached when desired.

These and other features of the invention, including certain details of construction and combinations of parts will be set forth in connection with an illustrative machine and pointed out in the appended claims.

Referring to the accompanying drawings, Figure 1 is a perspective of a machine in which the present invention is embodied; Fig. 2 is a cross section of a portion of the machine, and Fig. 3 is a detail perspective of the presenter and its mode of attachment to its carrier.

Mounted upon a base 1 is a receptacle 3, herein shown as cylindrical, and provided with an upwardly extending filling tube 5 by means of which the supply-of stiffening material in the reservoir may be replenished. Fastened to the reservoir by means of bolts 7 is a double track 9 upon which a carrier 11 is arranged to slide, said carrier having mounted near its outer end. a' presenter 13 which has formed upon opposite sides vertically. extending ribs 15. It will be noted that the presenter corresponds approximately in contour to that of thetoe portion of the vamp ofa shoe.

The presenter 13 is provided with a stem 17 which is received in a slot 19 in the carrier 11. The stem is provided on one side with a curved recess in which a portion of an eccentric 21 is normally held by means of a spring 27, said eccentric being mounted upon a stud 23 to which is attached a handle 25 .so that by manipulating this handle -Such removal is desirable since the stiffening material the base of which is commonly shellac, accumulates after a time upon the presenter and must be removed therefrom. The carrier 11 is connected by means of a pin 31 to a double link 33 the hub of which carries a rotatable stud 35 to which is fast the end 37 of an operating arm 39. The hub 41 of the arm 39 is rotatably mounted on a sleeve 43 which is an extension of the hub of a gear 45. The gear has a projecting clutch member 47 with which a properly shaped face on the interior of the hub 41 is adapted to cotiperate so that, viewing the machine as in Fig. 2, when the hub 41 is moved to the left the clutch faces are engaged. The inclination of the coiiperating clutch faces is so chosen that as soon as pressure upon the hub 41 to move it to the left is Withdrawn the clutch is no longer operative.

In order to move the hub 41 so as to connect the operating arm with the rotating gear a bell crank lever 49 is pivoted upon a shaft 51 and is operated by means of a treadle rod 53 which is connected at its lower end to a treadle 54, a spring 56 serving to keep the treadle normally raised. The upper arm of the bell crank lever 49- is provided with an elongated projection which acts against a hardened plate 57 on the end of the hub 41 and is shaped to be received in a slot 59 in said plate when said slot registers with said projection. The arm 39 is normally held in the position shown in the drawings by means of a spring 61 which is connected at its lower end through a rod with the pivot 63 of the treadle and at its upper end with a projection 65 on the hub 41. The gear meshes with a gear 69 on a driving shaft 78 which carries the usual fast and loose pulleys 80, 82.

With the mechanism which has thus far been described, and assuming that the gear 45 is being continuously rotated, the operation of the presenter is as follows: When the treadle is depressed the hub 41 is moved to the left as viewed in Fig. 2 thereby connecting said hub with the gear 45 through the clutch member 47. The arm 39 then moves with the gear 45 until the slot 59 registers with the elongated projection 55 whereupon the clutch is no longer effective. At this point in the operation of the machine, however, the elongated projection 55 having entered the slot 59 holds the arm 39 in itsforward position as long as the operator continues to hold the treadle depressed. A stop pin 10 carried by the bell crank 49, and movable in a slot in the bearing 12 of the shaft 51 limits the forward movement of said bell crank so as to permit the clutch to be inoperative while the projection 55 remains in the slot 59. The moment the treadle is released the projection 55 is withdrawn from the slot 59 and the spring 61 returns the arm 39 to its normal position. In order to cushion the arm 39 in its movements said arm is provided with buffer springs 70 which contact first with one and then with the other of the buffers 72. Movement of the arm 39 in the forward direction due to de pression of the treadle moves the presenter from its position in the reservoir out to the end of the double track 9- into a position readily accessible to the operator who then wipes off upon the inside of the toe portion of a vamp and the lining the stiffening material which is carried by the presenter. In order to supply stiffening material to the presenter when said presenter is in its nor mal position in the reservoir, a supplying member is fast to the shaft 67 by which the gear 45 is carried, said supplying member comprising a split hub 71 and radial arms 73 arranged in two sets which are spaced so as to receive the presenter 13 between them as they are revolved. These arms are of different shapes and lengths in order to stir up the stiffening material more effectively, l

and one or more of them is threaded through its respective portion of the split hub 71 and servesto hold said portion fast to the shaft 67.. To provide for access to the interior of the reservoir an extension of said reservoir is provided with a cover 79. In order to permit the presenter to move into and out of the reservoir and at the same time to prevent as far as practicable the accumulation of stiffening material upon said presenter, the reservoir is provided with a raised portion 81 on one side and at the top upon which are mounted two angle plates 83 in spaced relation so that a slot 85 is formed through which the presenter 13 may pass. The angle plates are formed at their sides with open ended slots 87 through which passscrew bolts 89 so that the plates may be adjusted to vary the Width of the slot 85. It will be understood that one pur- L Y pose of the rib 15 of the presenter 13 is to prevent the sides of the slot from scraping the presenter clean, and that the height of the rib 15 thus determines the thickness of the coating of stiffening material which is L not limited in, the scope of its application to the particular machine ShQWn and described.
